Brakes on fire
 
Ive noticed that when I drive my jeep on a longer drive maybe 25-30 miles on roads with stoplights that after a while one of my front wheels brakes will drag terribly. An interstate drive is fine, as long as I dont use the brakes heavily or very much. Its only the front wheels and is only one at a time. Any idea what this is all about?:banghead:

Sounds like the caliper slides are not sliding like they are supposed to or, the caliper piston is not releasing when you let off the brakes. Check your steel and also braided lines for signs of wear or damage. A bad line will also cause this to happen.

I agree with AllMudd, you have slides that are hanging up. I personally have never experience a brake line problem, other than being ripped out, that problem is obvious. Spend a couple hours on the weekend and pull the calipers, get some local parts-store caliper slide/bolt kits and install. Remember, speed gets you there, brakes get you home. Hang tough!!

I would lean towards a collapsed brake flex line, the brake fluid can be pushed into the caliper under assist, but the collapsed line will not let it return to the master cylinder. As you drive the heat from the brakes causes the fluid to expand and will apply the brakes even more. You may not see any external signs of damage either ! I would start there, they are a lot cheaper than calipers and given the age they should be replaced anyway.

The stock Jeep calipers crap out. There is no way around it. I have had my share of problems with the calipers. First my passenger side seized, then a couple months later my driver side. My driver side happened when I was driving home from about 10 miles away. When I got home my driver side rotor was actually glowing bright red like it had been heated by a torch, then it burst into flames. I hauled ass into my yard and grabbed the garden hose and put it out. I now keep a fire extinguisher in the Jeep. Best thing to do is to replace both calipers, rotors, pads, grease the slides, and bleed the crap out of your lines. You may get by a few months if you just fix the one you are having problems with, but from my experience once one goes the other is not far off. Something like brake it makes the most sense to spend the $200 and do everything.

yup... calipers most of the time.

If you crack open the bleeder screw and the brakes release, then its a pinched line.

But, most likely you can crack open the bleeder and the caliper will just sit there... locked up. I've replaced mine twice because of mud bogging. Even pulled 'em apart once and expanded the boots to clean them really good and they still frikin locked up so I replaced 'em a second time. Thats part of the reason why I don't go into mud bogs anymore... Some mud, heck yeah, but the mud with little tiny rocks in it, no way...
